## Includes

    #include <telepathy-glib/telepathy-glib-dbus.h>

## Description

dbus-glib's built-in factory functions for specialized GTypes need to do a fair amount of parsing on their arguments, so these macros are provided to avoid that. Each macro expands to a call to a function which caches the GType, so it only ever has to call into dbus-glib once.

tp_dbus_specialized_value_slice_new() is also provided.

## Functions

### tp_dbus_specialized_value_slice_new ()

    GValue *
    tp_dbus_specialized_value_slice_new (GType type);

#### Parameters

type | A D-Bus specialized type (i.e. probably a specialized GValueArray representing a D-Bus struct) |

#### Returns

a slice-allocated GValue containing an empty value of the given type.

<var>Currency</var> = <tt>&quot;GBP&quot;</tt> ), but could be represented by ( <var>Amount</var> = <tt>3210</tt> , <var>Scale</var> = <tt>3</tt> ,

<var>Currency</var> = <tt>&quot;GBP&quot;</tt> ) in a service that records balance in units of 0.001 pounds. </p>

<p> As a special case, if <var>Amount</var> = <tt>0</tt> ,

<var>Scale</var> = <tt>2**32 - 1</tt> (i.e. the largest possible 32-bit unsigned integer) and <var>Currency</var> = <tt>&quot;&quot;</tt> , this indicates an unknown amount. </p>

This macro expands to a call to a function that returns the GType of a GValueArray appropriate for representing a D-Bus struct with signature `(ius)`.

Member 0 (D-Bus type `i`, named `Amount`): <tp:docstring xmlns="http://www.w3.org/1999/xhtml"> <p>The amount, expressed as a fixed-point number with decimal scale defined by the <var>Scale</var> field; for instance, an <var>Amount</var> value of <tt>1234</tt> with <var>Scale</var> of <tt>2</tt> represents 12.34 in the currency unit given by the <var>Currency</var> field.</p>

Member 1 (D-Bus type `u`, named `Scale`): <tp:docstring xmlns="http://www.w3.org/1999/xhtml"> <p>The decimal scale for the fixed point value of the <var>Amount</var> field, defining the number of rightmost decimal digits from the integer value which form the fractional part of the resulting currency value.</p> <p>As well as defining the interpretation of <var>Amount</var>, user interfaces may use this value to determine the precision with which to display the amount.</p>

Member 2 (D-Bus type `s`, named `Currency`): The currency code represented by this amount, which SHOULD be an international currency code such as <tt>&quot;EUR&quot;</tt>, <tt>&quot;USD&quot;</tt>, or <tt>&quot;JPY&quot;</tt> if possible.

A mapping from contact handle to their capabilities.

This macro expands to a call to a function that returns the GType of a GHashTable appropriate for representing a D-Bus dictionary of signature `a{ua(a{sv}as)}`.

Keys (D-Bus type `u`, type `Contact_Handle`, named `Key`): A contact handle.

Values (D-Bus type `a(a{sv}as)`, type `Requestable_Channel_Class[]`, named `Value`): <tp:docstring xmlns="http://www.w3.org/1999/xhtml"> <p>The contact's capabilities. These should be represented in the same way as in <tp:dbus-ref namespace="org.freedesktop.Telepathy.Connection.Interface.Requests">RequestableChannelClasses</tp:dbus-ref>, except that they may have more fixed properties or fewer allowed properties, to represent contacts who do not have all the capabilities of the connection.</p> <p>In particular, requestable channel classes for channels with target handle type Contact MUST list <tp:dbus-ref namespace="org.freedesktop.Telepathy.Channel">TargetHandleType</tp:dbus-ref> among their fixed properties when they appear here, and clients MAY assume that this will be the case.</p> <tp:rationale> <p>This matches the initial implementations - service-side in telepathy-gabble, and client-side in telepathy-qt4 - and means that clients can use exactly the same code to interpret RequestableChannelClasses and contact capabilities.</p> </tp:rationale> <p>Channel classes with target handle type Handle_Type_Contact indicate that a request that matches the channel class, and also either has the contact's handle as <tp:dbus-ref namespace="org.freedesktop.Telepathy.Channel">TargetHandle</tp:dbus-ref> or the contact's identifier as <tp:dbus-ref namespace="org.freedesktop.Telepathy.Channel">TargetID</tp:dbus-ref>, can be expected to succeed.

### TP_STRUCT_TYPE_CONTACT_INFO_FIELD

    #define TP_STRUCT_TYPE_CONTACT_INFO_FIELD (tp_type_dbus_struct_sasas ())

The name of the field; this is the lowercased name of a vCard field. For example, a field representing a contact's address would be named &quot;adr&quot;.

This macro expands to a call to a function that returns the GType of a GValueArray appropriate for representing a D-Bus struct with signature `(sasas)`.

Member 0 (D-Bus type `s`, named `Field_Name`): The name of the field; this is the lowercased name of a vCard field. For example, a field representing a contact's address would be named &quot;adr&quot;.

Member 1 (D-Bus type `as`, named `Parameters`): <tp:docstring xmlns="http://www.w3.org/1999/xhtml"> <p>A list of vCard type parameters applicable to this field, with their values. The type parameter names, and any values that are case-insensitive in vCard, MUST be in lower case. For example, a contact's preferred home address would have parameters 'type=home' and 'type=pref'.</p> <tp:rationale> The type parameter 'type' is likely to be the most common, but there can be others, such as 'language=en'. </tp:rationale> <p>Characters which are required to be escaped in vCard type parameters should not be escaped in this list. For instance, a field &quot;X-FOO;SEMICOLON=\;:bar&quot; in a vCard would become ('x-foo', ['semicolon=;'], ['bar']) in this interface.</p> <tp:rationale> This avoids Telepathy UIs having to understand the escaping and unescaping rules for vCards. The type parameter name is not allowed (by RFC 2425) to contain an '=' character, so no ambiguity is introduced. </tp:rationale>

Consider the fields ['given-name', 'honorific-suffixes', 'family-name', 'honorific-prefixes']: does this represent two 'n' fields, or one with incorrect component ordering? </tp:rationale>

<tp:docstring xmlns="http://www.w3.org/1999/xhtml">

<p>A structure containing the required information to open a web-based e-mail UI, without needing re-authentication (if possible).</p>

<p>Because the URL and POST data frequently contain short-lived credential tokens, a new URL should be requested (by calling one of the methods that returns a Mail_URL) for each visit to the web-based UI, and the URL should be visited soon after it is returned.</p>

This macro expands to a call to a function that returns the GType of a GValueArray appropriate for representing a D-Bus struct with signature `(sua(ss))`.

Member 0 (D-Bus type `s`, named `URL`): The URL to which to send a request.

Member 1 (D-Bus type `u`, type `HTTP_Method`, named `Method`): The HTTP method of the request.

    #define TP_STRUCT_TYPE_HTTP_POST_DATA (tp_type_dbus_struct_ss ())

<tp:docstring xmlns="http://www.w3.org/1999/xhtml">

<p> A pair (key, value) representing POST data compatible with the application/x-www-form-urlencoded MIME type. The strings MUST be valid UTF-8 strings, and the characters used in the key MUST obey the requirements of the

<a href="http://www.w3.org/TR/html401/types.htmltype-cdata"> HTML CDATA type</a> . The value MUST NOT be encoded with HTML entities. </p>

<p>For example, if the POST data should contain a key &quot;less-than&quot; with value &quot;&lt;&quot;, and a key &quot;percent&quot; with value &quot;%&quot;, this should be represented as two HTTP_Post_Data structures, (&quot;less-than&quot;, &quot;&lt;&quot;) and (&quot;percent&quot;, &quot;%&quot;), resulting in a POST request whose request body is &quot;less-than=&amp;lt;&amp;percent=`25`&quot;. If a client passes this to a browser by writing it into an HTML form, it could do so by representing it as:</p>

<pre> &lt;input type=&quot;hidden&quot; name=&quot;less-than&quot;&gt;&amp;lt;&lt;/input&gt; &lt;input type=&quot;hidden&quot; name=&quot;percent&quot;&gt;%&lt;/input&gt; </pre>

<tp:rationale>

<p> This data can be used to generate a HTML file that will automatically load the URL with appropriate POST data, in which case the client MUST convert any characters that are special within HTML into HTML entities. Alternatively, it can be used in an API that will instruct the browser how to load the URL (like the Netscape Plug-in API), in which case the client MUST escape

<a href="http://www.ietf.org/rfc/rfc1738.txt">characters that are reserved in URLs</a> , if appropriate for that API. </p>

<p>An array of pairs is used instead of a map from keys to values, because it's valid to repeat keys in both HTML and x-www-form-urlencoded data.</p>

It is an error for a connection manager to put keys referring to the message as a whole in the second or subsequent Message_Part, or keys intended for body parts in the first Message_Part; clients MUST recover from this error by ignoring these mis-placed keys.</p> <tp:rationale> <p>Instead of representing messages as aa{sv} where the first dictionary is special (a dictionary of headers), we could have used a signature like (a{sv}aa{sv}) to separate out the headers and the body parts.</p> <p>However, this would make access to the messages more awkward. In Python, the syntax for access to a header field would remain <code>message0</code>, but access to a body field in the second body part would change from <code>message2 to message1['content']</code>. In GLib, the message would change from being a <code>GPtrArray(GHashTable)</code> to being a <code>GValueArray(GHashTable, GPtrArray(GHashTable))</code> which is rather inconvenient to dereference.</p> </tp:rationale> <p>In any group of parts with the same non-empty value for the <tt>alternative</tt> key (which represent alternative versions of the same content), more faithful versions of the intended message MUST come before less faithful versions (note that this order is the opposite of MIME <tt>multipart/alternative</tt> parts). Clients SHOULD display the first alternative that they understand.</p> <tp:rationale> <p>Specifying the preference order means that if the underlying protocol doesn't support alternatives, the CM can safely delete everything apart from the first supported alternative when sending messages.</p> <p>The order is the reverse of MIME because MIME's rationale for placing the &quot;plainest&quot; part first (legibility in pre-MIME UAs) does not apply to us, and placing the most preferred part first simplifies display (a client can iterate the message in order, display the first alternative that it understands, and skip displaying all subsequent parts with the same &quot;alternative&quot; key).</p> </tp:rationale> <p>Clients SHOULD present all parts that are not redundant alternatives in the order they appear in this array, possibly excluding parts that are referenced by another displayed part. It is implementation-specific how the parts are presented to the user.</p> <tp:rationale> <p>This allows CMs to assume that all parts are actually shown to the user, even if they are not explicitly referenced - we do not yet recommend formatted text, and there is no way for plain text to reference an attachment since it has no concept of markup or references. This also forces clients to do something sensible with messages that consist entirely of &quot;attachments&quot;, with no &quot;body&quot; at all.</p> <p>For instance, when displaying the above example, a client that understands the HTML part should display the JPEG image once, between the two lines &quot;Here is a photo of my cat:&quot; and &quot;Isn't it cute?&quot;; it may additionally present the image in some way for a second time, after &quot;Isn't it cute?&quot;, or may choose not to.</p> <p>A client that does not understand HTML, displaying the same message, should display the plain-text part, followed by the JPEG image.</p> </tp:rationale> <p>Connection managers, clients and extensions to this specification SHOULD NOT include <tp:type>Handle</tp:type>s as values in a Message_Part, except for <code>message-sender</code> in the header.</p> <tp:rationale> <p>Reference-counting handles in clients becomes problematic if the channel proxy cannot know whether particular map values are handles or not.</p> </tp:rationale> <h4>Example messages</h4> <p>A rich-text message, with an embedded image, might be represented as:</p> <pre> [ { 'message-token': '9de9546a-3400-4419-a505-3ea270cb834c', 'message-sender': 42, 'message-sent': 1210067943, 'message-received': 1210067947, 'message-type': 0, # = Channel_Text_Message_Type_Normal 'pending-message-id': 437, }, { 'alternative': 'main', 'content-type': 'text/html', 'content': 'Here is a photo of my cat:&lt;br /&gt;' + '&lt;img src=&quot;cid:catphoto&quot; alt=&quot;lol!&quot; /&gt;' + '&lt;br /&gt;Isn't it cute?', }, { 'alternative': 'main', 'content-type': 'text/plain', 'content': 'Here is a photo of my cat:\n[IMG: lol!]\nIsn't it cute?', }, { 'identifier': 'catphoto', 'content-type': 'image/jpeg', 'size': 101000, 'needs-retrieval': True, }, ]</pre> <p>telepathy-ring, Nokia's GSM connection manager, represents vCards sent via SMS as:</p> <pre> [ { 'message-token': '9de9546a-3400-4419-a505-3ea270cb834c', 'message-sender': 42, 'message-sent': 1210067943, 'message-received': 1210067947, 'message-type': 0, # = Channel_Text_Message_Type_Normal 'pending-message-id': 437, }, { 'content-type': 'text/x-vcard', 'content': [ 0x66, 0x69, 0x71, ...], # vCard data as an array of bytes }, ]</pre> <h3>Delivery reports</h3> <div> <p>Delivery reports are also represented as messages with the <tt>message-type</tt> header mapping to <tp:type>Channel_Text_Message_Type</tp:type> Delivery_Report.

If <tp:value-ref type="Call_State_Change_Reason">User_Requested</tp:value-ref> then the Actor member will dictate whether it was the local user or a remote contact responsible.

Member 2 (D-Bus type `s`, type `DBus_Error_Name`, named `DBus_Reason`): <tp:docstring xmlns="http://www.w3.org/1999/xhtml"> <p>A specific reason for the change, which may be a D-Bus error in the Telepathy namespace, a D-Bus error in any other namespace (for implementation-specific errors), or the empty string to indicate that the state change was not an error.</p> <p>This SHOULD be an empty string for changes to any state other than Ended.</p> <p>The errors Cancelled and Terminated SHOULD NOT be used here; an empty string SHOULD be used instead.</p> <tp:rationale> <p>Those error names are used to indicate normal call termination by the local user or another user, respectively, in contexts where a D-Bus error name must appear.</p> </tp:rationale>

Member 3 (D-Bus type `s`, named `Message`): An optional debug message, to expediate debugging the potentially many processes involved in a call. This may be communicated across the network in protocols that support doing so, but it is not essential.

### TP_STRUCT_TYPE_CANDIDATE

    #define TP_STRUCT_TYPE_CANDIDATE (tp_type_dbus_struct_usua_7bsv_7d ())

A Stream Candidate.

This macro expands to a call to a function that returns the GType of a GValueArray appropriate for representing a D-Bus struct with signature `(usua{sv})`.

Member 0 (D-Bus type `u`, type `Stream_Component`, named `Component`): The component number.

Member 1 (D-Bus type `s`, named `IP`): The IP address to use.

Member 2 (D-Bus type `u`, named `Port`): The port number to use.

Member 3 (D-Bus type `a{sv}`, type `Candidate_Info`, named `Info`): Additional information about the candidate.

### TP_STRUCT_TYPE_CANDIDATE_PAIR

    #define TP_STRUCT_TYPE_CANDIDATE_PAIR (tp_type_dbus_struct__28usua_7bsv_7d_29_28usua_7bsv_7d_29 ())

A Pair of candidates.

This macro expands to a call to a function that returns the GType of a GValueArray appropriate for representing a D-Bus struct with signature `((usua{sv})(usua{sv}))`.

Member 0 (D-Bus type `(usua{sv})`, type `Candidate`, named `Local`): The local candidate.

Member 1 (D-Bus type `(usua{sv})`, type `Candidate`, named `Remote`): The remote candidate.

### TP_STRUCT_TYPE_CODEC

    #define TP_STRUCT_TYPE_CODEC (tp_type_dbus_struct_usuuba_7bss_7d ())

A description of a codec.

This macro expands to a call to a function that returns the GType of a GValueArray appropriate for representing a D-Bus struct with signature `(usuuba{ss})`.

Member 0 (D-Bus type `u`, named `Identifier`): <tp:docstring xmlns="http://www.w3.org/1999/xhtml"> Numeric identifier for the codec. This will be used as the PT in the SDP or content description.

Member 1 (D-Bus type `s`, named `Name`): <tp:docstring xmlns="http://www.w3.org/1999/xhtml"> The name of the codec.

Member 2 (D-Bus type `u`, named `Clockrate`): <tp:docstring xmlns="http://www.w3.org/1999/xhtml"> The clockrate of the codec.

Member 3 (D-Bus type `u`, named `Channels`): <tp:docstring xmlns="http://www.w3.org/1999/xhtml"> Number of channels of the codec if applicable, otherwise 0.

Member 4 (D-Bus type `b`, named `Updated`): <tp:docstring xmlns="http://www.w3.org/1999/xhtml"> This should be set to true in calls to <tp:dbus-ref namespace="ofdT.Call1.Content.MediaDescription">Accept</tp:dbus-ref> and <tp:member-ref>UpdateLocalMediaDescription</tp:member-ref> if this codec has changed in a way that needs to be signalled over the network. If it is set to false, the CM is allowed ignore any differences between the current parameters and the previous ones <tp:rationale> This mechanism may be used to save bandwidth and avoid the CM having to calculate diffs against previous versions of this struct, which can lead to false-positives (e.g. redundant ptime updates). </tp:rationale>

Member 5 (D-Bus type `a{ss}`, type `String_String_Map`, named `Parameters`): <tp:docstring xmlns="http://www.w3.org/1999/xhtml"> Extra parameters for this codec.

### TP_STRUCT_TYPE_MEDIA_DESCRIPTION_OFFER

    #define TP_STRUCT_TYPE_MEDIA_DESCRIPTION_OFFER (tp_type_dbus_struct_oa_7bsv_7d ())

The remote description offer and its information

This macro expands to a call to a function that returns the GType of a GValueArray appropriate for representing a D-Bus struct with signature `(oa{sv})`.

Member 0 (D-Bus type `o`, named `Media_Description`): <tp:docstring xmlns="http://www.w3.org/1999/xhtml"> The object path to the <tp:dbus-ref namespace="ofdT.Call1.Content">MediaDescription</tp:dbus-ref>

Member 1 (D-Bus type `a{sv}`, type `Media_Description_Properties`, named `Properties`): The immutable properties of all interfaces of the codec description. <tp:rationale> Having all the codec description properties here saves a D-Bus round-trip - it shouldn't be necessary to get the properties from the MediaDescription object, in practice. </tp:rationale>

### TP_STRUCT_TYPE_STREAM_CREDENTIALS

    #define TP_STRUCT_TYPE_STREAM_CREDENTIALS (tp_type_dbus_struct_ss ())

A username and password pair.
